Nearly 60 percent of American adults may have hypertension, or may be on the verge of suffering the condition, as measured by recently revised high blood pressure classifications.
The finding, reported in the Oct. 25 issue of the Archives of Internal Medicine, comes from nationally representative health data analyzed by two University of Illinois at Chicago researchers. Youfa Wang, an assistant professor of human nutrition and Qiong Joanna Wang, a biostatistician at UIC’s School of Public Health, analyzed data collected for the Centers for Disease Control and Prevention’s 1999-2000 National Health and Nutrition Examination Survey.
The Wangs found that more than half of all adults surveyed (58.2 percent) had blood pressure readings that placed them into the categories of either hypertension or prehypertension, a new, lower-threshold designation set last year in the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure, known as JNC7. Prehypertension is indicated by systolic/diastolic readings of between 120/80 and 139/89. If either the systolic or diastolic blood pressure falls within this range, it indicates prehypertension. Hypertension remains defined as 140/90 or above in the JNC7 classifications.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
